Hi guys, I use AMD64 proccesor, instead of x86. I've copied all files listed in your list (x86 files changes into amd64 files) from Vista Ultimate installation to Windows Server 2008 Enterprise. I've also imported all the registry keys you've provided (also, modified to suit my proccesor) - had to grant administrators access to many keys. When I try to launch Media Center, I get the software restriction policy error (same as you wrote here). I trieid adding the HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsMediaCenter - MediaCenter (DWORD 32 BIT) = 0 value, but the error box keeps appearing and won't bother launcing my media center . Do you have any other suggestion how to KILL this message box ? Thanks ahead, Effy.
